CHARLES W'. BERNSON, OF NEV YORK, N. Y.

AUTOMATIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No; 650,164, dated May 22,1900.

Application filed January 19, 1900. Serial No. 2,015. (No model.)

T0 all whom t may concern:

Be it known that I, CHARLES W. BneNsoN, a citizen of the United Statesof America, and a resident of New York city, county and State of NewYork, have invented certain new and useful Improvements in AutomaticGas- Lighters, of which the following is a specilication.

My invention relates to automatic gas-lighters in which an ignitingbodyhaving the property of occludin g gas and generating heat is used forfirst igniting a small jet issuing from a by-pass of the gas-cock beforeopening the main passage, which ignites the main gas-jet when the cockis further opened 'and is cut off when the main passage is sufficientlyopened for use; and lny invent-ion consists in an improved constructionof the apparatus whereby it is simpler, cheaper, and neater than asheretofore constructed, as hereinafter described, reference being madeto the accompanying drawings, in which;

Figure l is a vertical sectional elevation of a gas-cock constructed andprovided with the igniting devices in accordance wit-h my invention andapplied to an ordinary burner. Fig. 2 is a horizontal section of thecock. Fig. 3 is a top- View. Fig. 4 is a vertical sectional elevation ina modified form of construction and applied to an incandescent burner.

The essential feature of my invention is in the construction of the pluga of the gas-cock with the by-pass'b for the igniting-jet formed in saidplug and leading directly into a socket or center bore of the upper endof the plug for attachment of the iguiting burner directly to the end ofthe plug, thus making simpler construction and better appearance and atthe same time permitting the usual adjusting-nut for the plug to beused. To this end I provide the small passage b from the exteriorsurface of the plug a little in adv Vance of the opening end of the mainpassage when the cock is partly opened, as represented in the drawings,the igniting-jet will escape through the by-pass and be ignited by thebody g. Themain jet will be ignited by the igniting jet when the cock isfurther opened and the igniting-jet will be cut ed.

In Fig. 1 the plug u, is constructed with an integral tubular extensionj for the connection of the burner f, and the nut t for tightening theplug is perforated and screws onto such extension in lieu of the usualtap-screw screwing into a socket of the plug. In Fig. 3 theextension-piece Zis formed separately from the plug and is screwed intoa tapped hole in the end of the plug, and nut k is similarly perforatedand screwed onto the extension-piece. Either of these constructions maybe used, as preferred. The cock so constructed is alike adapted for 10Wburners, as in Fig. 1, or higher ones, as in Fig. 4, with anintermediate extension-piece m for the high burners. The igniter, whichturns with the plug, is to be so mounted on the plug that it will occupythe best relation to the main jet for lighting it when the cock ispartly opened. That it is turned away from such position when the cockis further opened is of no consequence. In thisV construction no changewhatever is made with the shell of the cock, and the plug may be made aseasily and cheaply as the ordinary plug.

What I claim as my invention is- In an automatic gas-lighter comprisingan ignitingburner supplied with an ignitingjet through a branch issue ofthe cock controlling the main jet, and provided with an igniting-bodylocated in suitable proximity to the main burner-tip for igniting themain jet, the passage for the igniting-jet formed in the plug andcommunicating with a socket or center bore of the upper end of the plugand the igniting-burner attached directly to the end of the plug.

Signed by me at New York, N. Y., this 18th day of January, 1900.

CHARLES W. BERNSON.
